Description

Technical Field

[0001] The invention mainly relates to the technical field of production and processing of self-adhesive labels, and in particular to a safety line pressing device for self-adhesive labels. Background Art

[0002] Self-adhesive labels are composite materials consisting of a facestock, adhesive, and backing paper. They utilize pressure-sensitive adhesive for instant application. They offer advantages such as the absence of adhesive application, high adhesive efficiency, and strong adaptability, making them widely used in logistics, medicine, and product anti-counterfeiting.

[0003] During the production process of self-adhesive labels, metal or polyester fiber strips are embedded into the labels to achieve anti-counterfeiting security threads through micro-text or optical features. However, the traditional self-adhesive label security thread pressing process uses a continuous roller pressing method. Long-term contact causes the adhesive to migrate due to heat, affecting the adhesive performance. Therefore, there is an urgent need to develop a new self-adhesive label security thread pressing device. Summary of the Invention

[0021] Refer to the attached Figure 1-6 A self-adhesive label security line pressing device includes a base 1 and a support frame 2. The support frame 2 is provided with a reciprocating lifting mechanism 3. The reciprocating lifting mechanism 3 includes: A vertically extending rack 301 is slidably connected to the support frame 2 via a vertical guide sleeve 303; The sector gear 302 is driven to rotate and periodically meshes with the rack 301; A return spring 304 is sleeved on the rack 301, with the top end of the return spring 304 fixed to the vertical guide sleeve 303 and the bottom end abutting against the limiting bosses 305 integrally formed on both sides of the rack 301; The pressing block 4 is fixed to the bottom end of the rack 301 , and the pressing block 4 forms a periodic stamping fit with the pressing platform 5 provided on the top of the machine base 1 .

[0022] In this embodiment, the self-adhesive label being transported is attached to the top of the pressing platform 5, and the sector gear 302 is driven to rotate and periodically mesh with the rack 301. When the sector gear 302 is meshed with the rack 301, the rack 301 is driven to cooperate with the vertical guide sleeve 303 to slide upward and stretch the return spring 304. Until the sector gear 302 is disengaged from the rack 301, the return spring 304 is restored to drive the rack 301 to slide rapidly downward in the vertical guide sleeve 303, thereby cooperating with the pressing block 4 to quickly press the safety inside the self-adhesive label, thereby avoiding long-term contact causing heat migration of the adhesive and affecting the pasting performance.

[0023] Triangular reinforcement ribs 201 are provided at the intersection of the horizontal beam and the vertical beam of the support frame 2 and at the bottom connected to the machine base 1.

[0024] A driving gear 306 is rotatably mounted on the support frame 2 , one end of the driving gear 306 is connected to a driving motor 307 , and the driving motor 307 is fixed to the support frame 2 via a mounting base 308 . The driving gear 306 is meshedly connected to a transmission gear 309 , and the transmission gear 309 rotates coaxially with the sector gear 302 .

[0025] In this embodiment, after the driving motor 307 is started, the driving gear 306 is driven to rotate synchronously, and cooperates with the meshing transmission to drive the transmission gear 309 to rotate. The sector gear 302 and the transmission gear 309 rotate synchronously to drive the rack 301 to slide back and forth in the vertical guide sleeve 303.

[0026] The transmission gear 309 is rotatably connected to the support frame 2 through the first transmission shaft 310. A second transmission shaft 311 is coaxially arranged inside the first transmission shaft 310, and an axially extending mating key 312 is provided on the outer wall of the second transmission shaft 311. The mating key 312 is slidably engaged with the mating groove 313 opened on the inner wall of the first transmission shaft 310. There are multiple sector gears 302 with different numbers of teeth, and they are all fixed on the second transmission shaft 311; the end of the second transmission shaft 311 away from the sector gear 302 is rotatably connected to a connecting plate 314, and a first guide slide rod 315 for sliding engagement and a first screw rod 316 for rotation engagement are provided on the connecting plate 314. The first guide slide rod 315 and the first screw rod 316 are both parallel to the second transmission shaft 311, and are respectively fixedly connected and rotatably connected to the support frame 2.

[0027] In this embodiment, after rotating the first screw rod 316, the connecting plate 314 can be driven to slide on the first guide rod 315, and the second transmission shaft 311 can slide synchronously. The second transmission shaft 311 then cooperates with the matching key 312 to slide in the matching groove 313. The sliding cooperation between the matching key 312 and the matching groove 313 can also ensure that the transmission gear 309 and the sector gear 302 rotate coaxially. Each sector gear 302 slides synchronously following the second transmission shaft 311, and since each sector gear 302 has a different number of teeth, it can drive the rack 301 to rise to different heights, thereby stretching the spring 304 to different lengths, and then the pressing strength of the pressing block 4 can be adjusted to cooperate with the pressure of self-adhesive labels of different specifications.

[0028] A wrinkle removal mechanism 6 is provided on both sides of the pressing platform 5, and the wrinkle removal mechanism 6 includes a rotating frame 601, and the bottom of the rotating frame 601 is equipped with a wrinkle removal roller 602, and the top is fixedly installed with a movable rod 603, and the movable rod 603 is vertically slidably matched with the movable plate 604, and the movable plate 604 is driven to move in the horizontal direction; two symmetrically distributed fixed rods 605 are horizontally slidably matched with the movable plate 604, and the ends are assembled on the mounting plate 606, and the mounting plate 606 is also equipped with an electric telescopic rod 607, and the telescopic end of the electric telescopic rod 607 extends in the horizontal direction and is fixedly connected to the movable plate 604; a guide rail 608 is fixed on the mounting plate 606, and the guide rail 608 is slidably matched with the guide column 609 fixed on the movable rod 603, and the guide rail 608 includes a horizontal portion 610, an inclined portion 611 and an arc portion 612 that guides the two to be connected.

[0029] In this embodiment, after the electric telescopic rod 607 is activated, the movable plate 604 cooperates with the fixed rod 605 to stably drive the rotating frame 601 to move horizontally outward. During this process, the guide column 609 will first slide in the inclined portion 611, thereby cooperating with the sliding of the movable rod 603 and the movable plate 604 to drive the rotating frame 601 to descend. When the guide column 609 passes through the arc portion 612 and enters the horizontal portion 610, the rotating frame 601 stops descending and only moves synchronously with the electric telescopic rod 607. The wrinkle removal roller 602 maintains synchronous movement, thereby first pressing the self-adhesive label and then rolling on its surface to remove wrinkles.

[0030] The mounting plate 606 is provided with a second guide rod 613 for sliding engagement and a second screw rod 614 for rotational engagement. The two guide rods 613 and the second screw rod 614 for rotational engagement both extend in a vertical direction and are fixedly connected and rotationally connected to the support frame 2 respectively.

[0031] In this embodiment, after the second screw rod 614 is rotated, the mounting plate 606 can be driven to slide and rise on the second guide rod 613, and the wrinkle removal roller 602 keeps moving synchronously, which is used for self-adhesive labels of different thicknesses.

It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent of the present invention shall be based on the attached claims.
